Summary
Endoscopic pituitary surgery offers comparable tumor outcomes to open surgery with improved rhinology quality of life. This minimally invasive technique also resulted in shorter hospital stays and fewer complications.
Area of Science:
- Neurosurgery
- Otolaryngology
- Endocrinology
Background:
- Pituitary surgery is a common procedure for treating various pituitary adenomas.
- Traditional open surgery approaches can lead to significant morbidity, particularly affecting rhinology-specific quality of life.
- Endoscopic techniques have emerged as a less invasive alternative, prompting investigation into their comparative efficacy and patient outcomes.
Purpose of the Study:
- To compare the rhinology-specific quality of life and tumor outcomes between endoscopic and open approaches to pituitary surgery.
- To evaluate complication rates, hospital stay duration, and functional recovery in patients undergoing either surgical method.
Main Methods:
- A retrospective analysis of pituitary surgery cases from January 1998 to February 2008.
- Inclusion of an inception cohort of endoscopic procedures and consecutive open procedures.
- Utilized the Sino-Nasal Outcome Test-22 (SNOT-22) to assess rhinology-specific quality of life.
Main Results:
- Endoscopic surgery (71 cases) showed comparable tumor recurrence rates (18.2%) to open surgery (122 cases, 28.4%).
- Endoscopic procedures had significantly shorter hospital stays (4.1 days vs. 6.0 days; p <0.001) and improved rhinology-specific quality of life scores (6.5 vs. 9.2; p = 0.03).
- Complication rates were similar, though cerebrospinal fluid leaks were more frequent with endoscopy, while prolonged diabetes insipidus was more common with open surgery.
Conclusions:
- Endoscopic pituitary surgery provides tumor outcomes comparable to open surgery.
- The endoscopic approach significantly improves rhinology-specific quality of life compared to open surgery.
- Endoscopic surgery offers a safe and effective alternative with benefits in terms of hospital stay and quality of life.
